MLD Snooping Querier
4.4.11.1
Configuration
Use the MLD Snooping Querier Configuration page to configure the global MLD
snooping querier settings on the device. MLD snooping requires that one central
switch or router periodically query all end-devices on the network to announce their
multicast memberships. This central device is the MLD querier. When Layer 3 IP mul-
ticast routing protocols are enabled in a network with IP multicast routing, the IP mul-
ticast router acts as the MLD querier. However, if the IP- multicast traffic in a VLAN
needs to be Layer 2 switched only, an IP-multicast router is not required. The MLD
snooping querier can perform the MLD snooping functions on the VLAN.

Description
Item
Description
Admin Mode
The administrative mode for the MLD snooping querier on the device.
When enabled, the MLD snooping querier sends out periodic MLD
queries that trigger MLD report messages from the switches that want
to receive IP multicast traffic. The MLD snooping feature listens to
these MLD reports to establish appropriate forwarding.
IPv6 Address
The snooping querier unicast link-local IPv6 address to be used as the
source address in periodic MLD queries. This address is used when no
IPv6 address is configured on the VLAN on which the query is being
sent.
MLD Version
The MLD protocol version used in periodic MLD queries.
Query Interval (Sec-
onds)
The amount of time the MLD snooping querier should wait between
sending periodic MLD queries.
Querier Expiry Inter-
val (Seconds)
The amount of time the device remains in non-querier mode after it has
discovered that there is a multicast querier in the network.
